Latest Patents

Robert G Johnston holds a patent for a Multi-driver in-phase bipolar array loudspeaker. This loudspeaker system addresses the limitations of previous bipolar loudspeaker designs, where front and rear-mounted drivers were connected in the same electrical phase. His invention compensates for the undesirable cancellation and reinforcement effects that occur due to the interaction of the front and rear acoustical outputs over certain frequency ranges. By introducing a third side-mounted driver in an enclosure, Johnston's design mitigates the usual cancellations and reinforcements of acoustic levels that typically plague earlier bipolar loudspeaker systems. The use of electronic, electrical, and acoustical frequency-dividing networks allows for a nearly constant acoustic level across the entire operating range of the loudspeaker. This innovative arrangement results in a bipolar radiating characteristic that avoids the peaks and dips in acoustical output caused by the interaction of the drivers.
